I will suggest to buy CARDANO(ADA) because Cardano is a decentralised public blockchain and cryptocurrency project and is fully open source. Cardano is developing a smart contract platform which seeks to deliver more advanced features than any protocol previously developed.And looking at the coin cardano was just 0.11@ before one month and now its trading at 1$ mean almost 10x times rose. So I see that cardano will touch 2$ in next 2-3 months.Also you can go for steller, Tron, Verg.
